` FUEL-size INmcirroa. Y

itin Stimuli nitriet in in tlptetters utmt 'mit inaliwiiigvptt tf the stuff l TO ALL WHOM IT- MAY CONCERN:

Be it known that I, JOHN GIBSON, Jr., of the oity of Albany, county of Albany,l and State'of-New York, have invented a new and useful device, whereby the size of fuel proper to beused in a stove,l1eaier, or furnace, or the like, shall beindicated by a representation of the size of Vsuch fuel upon some part or appendage'of such stove, heater, furnace, or the like; and I do hereby declare that the following isla full, clear, and exact description thereof, .reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a section of a stove'or heater with such device thereon. d I

Figure 2 represents-a similar device made vin outline, indicating size of fuel to be used.

Figure 3 represents a device for indicating size of fuelby stating measurement in inh esor the like.

lThe nature of my invention consists in aixing'toa stove, heater, furnace, or the like, or in alnxing to any of the appurtenances ther-cof, any representation of the size of fuel proper to lie-used in such stove or heaterr Such representations of size may be fac-similes in size and form of such fuel, and may be made of metal,

either struckor cast, and attached to any portion of the stove or heater, or to any of its appendages, or may be cast solid with said stove or heater, or any partI thereof. I

Or, instead of the full facsimile form and size of fuel, outline sizesonly may be used, as aforesaid.

Or, again, measurement only may he lgiven, as,f o r instance, .Use coal l-in. diam, f2-in. diam, or any equivalent indication of size. l y

. In connection with the aforesaid visible indication or representation of size of fuel proper to be used, there' may beaixed or used words, in one or more languages, as Use this size coal, or equivalent words. These words or directions may be connected with and form a part ofthe piece on which the visible sizes of fuel are represented, or may be placed or used elsewhere on said stove, heater, or appendages thereof.

To enable others skilled inthe artV to make and use this invention, Lwill proceed to describe it, in reference to the accompanying drawings," and thelletters of reference marked thereon, the same letters indicating like parts. A, fig. l, represents a section-of 4aistove or'heater, with the fac-simile representations, a a a, of form and -size offuel to he used.

These representations, a a a, may be struck or east, and attached to stoves andthe like, or may be cast solid withsaid stoves, or any appendage thereof. i i

Or,'as in iig. 2, outline-size representations,=b b b, may be used, instead of the fac-simile representa-- tions a a a.

Or representations, as c, iig. 3, indicating'nieasurement of sizie of fuel by figures, or equivalents,'may be used; .and any of these visible representations or equivalents, on anystove, heater, or furnace, would indicate the proper size of fuel to be used, corresponding with the construction of such stove or heater, as designed'by the manufacturer.

To give` force and make explicit the Vvisiblc-sizerepresentations, a, b, or c, of fuel proper to be used, I connectfwitli said representations the words del, or equivalent directions.

The said words may be in onevor more languages, and may lie struck or cast, and form a part of the same piece with the size representations a, b,or c, or maybe separate from such representations, and located in any other suitable place on saidgstove or heater, or its appendages.

If desirable, any of the size representations, a`b, or c, may be made on a detachable piece, either with or without the accompanying words,-dd, and such detachable piece may b e used te carry to the coal-dealer, to order correct size of fuel by. `v

As the-.perfect combustion ofithe fuel, and thesatisfactory working of '1. stove orl heater, depend, in a great'degreo, upo`n using fuel of a size 4corresponding with its fire-pot and grate, manufacturers have, in many cases, attached to their stoves or heaters, directions, as follows, viz,"Us'e nut-coal, .Uselchestnut-coal, Use egg-sizecoaland lthe like; and"`as these terms, in many localities, do-not indicate the proper size of fuel intended to be used by the manufacturer of thestoves ory heaters, this non-agreementpf the size ofv fuel with the construction of the stove or heater often leads to the condemnation and rejection of such stove or heatert whereas a positivo representation, as a, b, or c, of the proper s ize of fuel, attached to any part of' the stove for its appendages, and coupled with the worded directions d d, in English, German, French, or other language, would, in all parts of the country, give to people of different nationalities positive, pointed, and infallible directions as to the proper size of fuel to be used in such stove or heater. A*

When the size-fuel. representation, with or without the worded directions, is made detachable,.such"sze representation could be carried andshown to the coal-dealer, as unmistakably indicating the size of coal wantedr for such stove or heater.

Or, if outline or measurement-size fuel representations are permanently attached, such size representations mayl be 'transferred to paper by placing said paper in contact with such size representation of fuel, and rlhbin'g said paper while in contact, and this paper could be taken to a coal-dealer, as indicating Acorrectly the size of fuel wanted.

Having described my inventioru/I do not claim the use of directions, by terms, on stoves or heaters, such as Use nut-size coal, Use egg-coal,4 &c., as they have'been used; but

What I claim, and desire to secure by'Letters Patent, is

1. The size-representaticns, a a a, of fuel, fac-similes in form and size, or outline-size representations b b, or measurement-size representation c, or any fuel-size representations equivalent thereto, cast solid with or attached yto any stove, heater, furnace, or the like, or cast with or attached to any part`or appendage of such stovevor heater, as and for the purposeset forth and described. l

2. The fu'elsize representations or indications a,`b, or c, ortheir equivalcntsfattaehed permanently to anyy stove or heater, orwhen made detachable, cithe'r with or without thc words d al, or their equivalents, as and for the -purpose set forth and described. i

8. The words d d, or their equivalents, in one or more languages, when used on any stove or heater, or on representation, `asand for the purpose set forthand described.

any appendage thereof, in connection with a fuel-size representation, a, b, or c, or their equivalent lfue1size l JOHN GIBSON, JR. Witnesses ALEXANDER SELKIRK, J. H. GnzsoN.
